Question

我在javascript中为精神发育迟滞的人制作了一个小网页（和应用）。有一些图像可供点击。当他们这样做时，他们会听到说出一些文字的声音。现在我想阻止他们在语音结束讲话之前点击。所以声音不会混淆。我想用Event.stopPropagation()做到这一点。我该怎么做？还有更好的方法吗？

	function klok()
	{ 
	responsiveVoice.cancel();
	var today = new Date();
  var h = today.getHours();
  var m = today.getMinutes();
	var pause = 7000;
  setTimeout(function(){ responsiveVoice.speak(" het is nu "+h+" uur en "+m+" minuten",'Dutch Female', parameters2); },100);
	}

function voiceStartCallback() {
    console.log("Voice started");
		color = "red";
    document.body.style.background = color;
}
function voiceEndCallback() {
    console.log("Voice ended");
		color = "black";
    document.body.style.background = color;
}
function voiceEndCallback2() {
    console.log("Voice ended");
		color = "white";
    document.body.style.background = color;
}
var parameters = {
    onstart: voiceStartCallback,
    onend: voiceEndCallback
}
var parameters2 = {
    onstart: voiceStartCallback,
    onend: voiceEndCallback2
}
</script>
</body>
</html>
